Alumina porous ceramics: mathematical behavior at different commercial starch concentration
(Trans Tech Publications Ltd, 2008-01-01)
Several researches have been developed in order to verify the porosity effect over the ceramic material properties. The starch consolidation casting (SCC) allows to obtain porous ceramics by using starch as a binder and ...
Emerging Materials and Platforms for Biosensor Applications
(CRC Press - Taylor & Francis Group, 2020)
Different materials are used for fabrication of biosensors based on their applications and other considerations as sample type and cost, among others. Biosensors can be miniaturized since microscale devices offer several ...
Designing Colloidal Silica-Bonded Porous Structures of In-situ Mullite for Thermal Insulation
(2020-09-01)
Abstract: Colloidal silica (CS) is a promising raw material for refractory castable ceramics. It consists of stable suspensions of synthetic amorphous silica nanoparticles that behave simultaneously as liquid medium and ...

Influência da anodização pulsada nas propriedades da alumina anódica porosa (AAP)
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-SoCâmpus Sorocaba, 2017-04-27)
Porous anodic alumina can be obtained, in addition to conventional methods such as potentiostatic and galvanostatic, or by pulsed method. Among these are the methods of discontinuous pulse, hybrid pulse and polarized pulse ...
Optical performance of hybrid porous silicon-porous alumina multilayers
(American Institute of Physics, 2018-05)
In this work, we study the optical response of structures involving porous silicon and porous alumina in a multi-layered hybrid structure. We performed a rational design of the optimal sequence necessary to produce a high ...
Anodização para obtenção de membranas cerâmicas

properties necessary for the application as a ...
Estudo da alumina anódica porosa como sensor para diferentes gases
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2013-04-18)
In this project we studied the porous anodic alumina as a possible application in gas sensors with high sensitivity. Initially we seek a configuration of anodic porous alumina (PA) and the type of gas or vapor in which ...
Aluminas macro-mesoporosas produzidas pelo método sol-gel para aplicação em catálise heterogênea
(Universidade Estadual Paulista (Unesp), 2015-07-22)
Alumina is an important support for heterogeneous catalysts. The matching of appropriate alumina physical properties and controlled textural properties can improve its performance as support in catalysis applications. ...
Preparation of hierarchically structured porous aluminas by a dual soft template method
(Elsevier B.V., 2010-07-01)
A general and potentially easy method of synthesizing aluminas possessing hierarchical pore structure is presented in this paper. This method is based on the integration of the sol-gel process with micelles of poly(ethylene ...
